How to Run a QIS DHT Node in 15 Minutes

The Quadratic Intelligence Swarm (QIS) DHT network is live. Two nodes are running as of April 2026 — one operated by the protocol team, one by an early adopter. This is how you become node three.

This isn't a theoretical walkthrough. By the end of this guide you'll have a running DHT node that connects to the live Kademlia network, generates and stores Ed25519 keypairs, and can both deposit outcome packets and query peer outcomes. Total time: under 15 minutes if you have Node.js installed.

What You're Actually Running

A QIS DHT node is a peer in a Kademlia-based distributed hash table. It does three things:

1. Holds a slice of the network's keyspace — based on your node's XOR distance to each topic bucket
2. Accepts and stores outcome packets — cryptographically signed JSON blobs that encode what worked, under what conditions
3. Responds to peer queries — when other nodes ask "what do you know about topic X?", your node answers

The math that makes this interesting: with N nodes in the network, there are N(N-1)/2 synthesis paths. Add node 3 and you don't add 1 path — you add N-1 paths simultaneously. With 300 nodes (OHDSI Rotterdam scale), that's 44,850 synthesis paths. This is the quadratic property that gives QIS its name.

Your node contributes to that network the moment it comes online.

Prerequisites

• Node.js 18 or later
• npm 9 or later
• About 50MB of disk space
• An internet connection that allows outbound TCP (for Hyperswarm peer discovery)

Check your versions:

node --version   # should be v18.x or higher
npm --version    # should be 9.x or higher

Step 1: Install the YonderClaw Package

YonderClaw is the reference Node.js implementation of a QIS DHT node. Install it globally to get the yonderclaw CLI:

npm install -g create-yonderclaw

Or install as a project dependency:

npm install create-yonderclaw

Verify the install:

yonderclaw --version

Step 2: Generate Your Node Identity

Each QIS node has an Ed25519 keypair. The public key becomes your node ID on the network. Your node ID determines which slice of the Kademlia keyspace you're responsible for — this is calculated by XOR distance to each of the 119 topic buckets.

Generate your identity:

yonderclaw init

This creates:

• ~/.yonderclaw/identity.json — your Ed25519 keypair (keep the private key secret)
• ~/.yonderclaw/config.json — node configuration
• ~/.yonderclaw/db/ — SQLite database for packet storage

Your public key will be displayed:

✓ Identity generated
  Node ID: 8f3a2b1c4d5e6f7a8b9c0d1e2f3a4b5c...
  Keyspace: responsible for 119/119 buckets until peers join
  Config: ~/.yonderclaw/config.json

Note: Your node starts responsible for all 119 buckets because you're the first peer (locally). As more peers connect, Kademlia re-distributes the keyspace automatically via XOR routing. This is self-organising — you don't need to configure it.

Step 3: Start the Node

yonderclaw start

On first start, Hyperswarm broadcasts your node to the DHT discovery layer. Within 30-60 seconds, you'll see peer connections being established:

[2026-04-19T16:00:00Z] QIS DHT Node starting...
[2026-04-19T16:00:01Z] Hyperswarm listening on topic: qis-protocol-v1-mainnet
[2026-04-19T16:00:23Z] Peer connected: 4a7b2c1d... (distance: 0x2f1a...)
[2026-04-19T16:00:24Z] Keyspace rebalanced: 62/119 buckets (was 119/119)
[2026-04-19T16:00:24Z] Node online. Ready to deposit and query.

The keyspace rebalance is Kademlia working correctly — when you connect to an existing peer, the network redistributes which topics each node is closest to. You'll hold roughly 119 / peer_count buckets, each peer holds the rest.

Step 4: Deposit Your First Outcome Packet

An outcome packet is a structured JSON blob that says: "In context C, action A produced outcome O, with confidence P." It's the unit of intelligence in QIS.

Deposit a packet from the CLI:

yonderclaw deposit \
  --topic "ml.training.convergence" \
  --context '{"model": "transformer", "dataset_size": "10GB", "optimizer": "adamw"}' \
  --outcome '{"loss_final": 0.0023, "epochs": 47, "converged": true}' \
  --confidence 0.94

The node will:

1. Sign the packet with your Ed25519 private key
2. Hash the packet to determine its position in the keyspace
3. Route it to the responsible peer via Kademlia XOR routing
4. Confirm storage

✓ Packet deposited
  Topic: ml.training.convergence
  Packet ID: 7c2d4f1a...
  Routed to: 3 peers (quorum = 3)
  Signed: Ed25519 / your-node-id

The packet is now available to any peer that queries ml.training.convergence. They don't get your raw dataset — just the outcome summary you chose to share.

Step 5: Query Peer Outcomes

To query what the network knows about a topic:

yonderclaw query --topic "ml.training.convergence" --limit 10

Output:

[
  {
    "packet_id": "7c2d4f1a...",
    "depositor": "8f3a2b1c...",
    "topic": "ml.training.convergence",
    "context": { "model": "transformer", "dataset_size": "10GB", "optimizer": "adamw" },
    "outcome": { "loss_final": 0.0023, "epochs": 47, "converged": true },
    "confidence": 0.94,
    "signature_valid": true,
    "timestamp": "2026-04-19T16:01:00Z"
  }
]

Each packet includes a signature_valid field — the node cryptographically verifies each Ed25519 signature before returning results. You can trust the data came from the stated node ID and hasn't been tampered with.

Step 6: Run as a Background Service (Optional)

For persistent operation, run your node as a system service so it stays online between reboots:

Linux / macOS (systemd):

yonderclaw install-service
systemctl enable yonderclaw
systemctl start yonderclaw

macOS (launchd):

yonderclaw install-service --launchd

Windows:

yonderclaw install-service --windows-task-scheduler

Check status:

yonderclaw status

What Your Node Contributes

Once running, your node:

• Holds packets for the topics closest to your node ID in XOR space
• Routes queries — when a peer asks for a topic you don't hold, you return the 3 closest peers to that topic (Kademlia k-bucket routing)
• Adds synthesis paths — each new node multiplies the network's intelligence surface quadratically
• Participates in replication — packets with quorum=3 are stored on 3 nodes, so the network is resilient to any single node going offline

You don't need to do anything special to contribute. Running the node is the contribution.

Architecture: What's Happening Under the Hood

The QIS DHT is built on three layers:

┌─────────────────────────────────────────────────┐
│  Application Layer (your domain: ML, health,    │
│  VLBI data, genomics — any outcome packets)     │
├─────────────────────────────────────────────────┤
│  QIS Packet Layer (Ed25519 signing, outcome     │
│  schema validation, topic bucketing)            │
├─────────────────────────────────────────────────┤
│  Kademlia DHT Layer (XOR routing, k-buckets,    │
│  Hyperswarm peer discovery, replication)        │
└─────────────────────────────────────────────────┘

Hyperswarm handles peer discovery — nodes announce themselves on a shared topic hash and establish direct encrypted connections without a central signalling server. There's no "QIS bootstrap server" that can go down and kill the network.

Kademlia XOR routing determines which node holds which packets. Your node ID is your Ed25519 public key. Distance between two node IDs is calculated by XOR. Every topic is mapped to the 3 nodes closest to it in XOR space. When a peer joins or leaves, each node independently rebalances — no coordination required.

SQLite storage (with sql.js fallback for environments without native binaries) holds your portion of the packet store locally. The database is yours — you can query it directly, back it up, or inspect it with any SQLite tool.

Programmatic API

If you're integrating QIS into your own application, the Node.js API gives you full control:

import { QISNode } from 'create-yonderclaw';

const node = new QISNode({
  identity: '~/.yonderclaw/identity.json', // or generate inline
  storage: './qis-data/packets.db',
  network: 'mainnet' // or 'testnet' for development
});

await node.start();

// Deposit an outcome
await node.deposit({
  topic: 'clinical.trial.outcome.diabetes',
  context: {
    intervention: 'GLP-1 agonist',
    cohort_size: 340,
    duration_weeks: 52,
    region: 'northwest-europe'
  },
  outcome: {
    hba1c_reduction: 1.4,
    adverse_events_pct: 3.2,
    dropout_rate: 0.08
  },
  confidence: 0.91
});

// Query peer outcomes for the same topic
const outcomes = await node.query('clinical.trial.outcome.diabetes', {
  limit: 20,
  min_confidence: 0.8,
  verify_signatures: true
});

console.log(`Found ${outcomes.length} peer outcomes`);

// Get network stats
const stats = await node.networkStats();
console.log(`Peers: ${stats.peers} | Buckets held: ${stats.bucketsHeld}/119 | Packets stored: ${stats.packetsStored}`);

await node.stop();
